PETER M. BOECK, OF SOUTH BEND, INDIANA, ASSIGNOR TO THE MALLEABLE STEEL RANGE MANUFACTURING (30., OF SOUTH BEND, INDIANA, A CORPORATION OF INDIANA..

PILOT-LIGHTER.

To all whom it may concern I Be it known thatI, PETER M. BoEoK, a citizen of the United-States,

Joseph and State of Indiana,-have invented certain new and useful Improvements in of which the following is a' provide a construction of the' above charac ter which is provided with a separate mixing and ignition chamber so divided as to traverse of gas in the pilot lighter; which insures of the gas being at all times plentifully supplied with air for mixing; to provide a construction iniwhich the ignition gases pass freely alon a pair of diverging arms or wings exten ing beneath the burners and which can'escape freely therefrom at all times and points throughout the length of said wings to pnovide a construction which can be readily applied to standard types of gas ranges or stoves and in general to provide an improved construction of the character referred towhich is economically and simply manufactured.

The invention consists in the matters hereinafter described and more particularly pointed out in the appended claims. I

In the drawings-Figure 1 is atop plan View of a pair of gas burners with my improved pilot lighter applied thereto; Fig. 2 is a side elevation of the construction shown in Fig. 1; Fig. 3.is-a rear end elevation of my pilot lighter with the burner pipes shown in section; Fig. 4 is a transverse sec- .tional viewtaken onlines 4-4 of Fig. 2. and

looking in thedirection on an enlarged scale. 4

Referring to the drawings1 and 2 designate a pair of foraminated burner pipes apertured as shown at 3, 3..

and resident of. the city of South Bend, in the county of St.

duit 12. The latter cocks of the burner tubes Patented Sept. 16,1913.

stove or range is inserted my improved pilot lighter, designated as a whole 9. This pilot ter comprises a pair of diverging wings or arms 10 and 11 and a main supply coir is divided nto a mixing chamber 13 and ignition chamber l t, hv means of a horizontal bridge wall or ballle plate 15, the inner end of which terminates short of the rear end of the conduit as shown more clearly in Fig. 2. The mixing chamber 13 communicates at its front end with a gas supply pipe 16 controlled by a turn cock 1 ear its front end the mixing chamber 13 is notched or-apertured as shown at. 1.8 to provide an air inlet. The upper end of the ignltioncham'ber 14 is longitudinally slotted throughout its length as shown 1b to permit the escape of sufficient gas for ignition. The wings 10 and 11 diverge downwardly and outwardly as shown in Fig. 3, so that their outer ends are adjacent the fol-aminated portions of the burners 1 and 2. At

their upper ends these wings are each provided with a series of ports 20, 20 to permit free escape of gas from the wings. All of these ports 20 above the wings are provided with an over-hanging ledge or flange 21 which extends throughout the full length of the wings. In order to readily secure the pilot lighter to the range, it is preferably provided with a pair of lugs which are fastened to the wall 8 by screw bolt 23.

The operation of the device is well understood. Gas is admitted by opening the urn and pilot lighter and a match applied to the slot 19. This instantly lights the burners through the ports in the wings 10 and 11. The pilot lighter is then of course cut oil. It will be noted that only a relatively small amount of gas is permitted to escape through the slot 19 while themain supply of gas in the chamber 13 is thoroughly mixed with the incoming air before the gas is ignited. The back and forth traverse of the gas as well as theprovision for its free escape through the wings prevents any back flash which the chief ditliculty and danger with pilot lighters.

The invention is not limited to the details of construction shown except as set forth in the appended claims.

.I claim as my invention: 1. A pilot lighter comprising-amain i'nl:- conduit, a baflie plate dividing said conduit into a mixing chamber and an ignition chamv sai main-conduit, each arm being provided copies of this patent maybe obtained for with a plurality of ports at its. inner face and having a flange overhanging said. ports.

2. A pilot lighter comprising a main inlet conduit, :1 pair of diverging arms connected to the end of said main conduit,""iibaiile plate extending from the entrance end of said main conduit to within a short distance of said arms for dividing said main conduit into a mixing chamber and an ignition chamber, an air inlet for the mixing cham-.

ber, the upper Wall of said main conduit having an ignition outlet from said ignition chamber and said arms having each ignition outlets through their inner walls, and a flange on each arm overhanging. the ignition outlets therethrough. w
